Active magnesium oxide is a relatively common green and low-carbon environmental protection material for soil reinforcement,which is often used in geotechnical engineering,building engineering and other fields.The active magnesia carbonated solidified silty clay was modified and prepared with coconut shell fiber from natural plant fiber.The comprehensive properties of the modified clay were tested by experiment.The results show that the addition of coconut shell fiber can significantly improve the mechanical properties of activated magnesia carbonated solidified silty clay.When the content of coconut shell fiber is 0.3%,the compressive strength and shear strength of activated magnesia carbonated solidified silty clay are the highest,but when the content of coconut shell fiber exceeds 0.4%,the improvement effect gradually decreases.
